The AT165 is designed to be used for both metal ARC (MMA) and TIG welding (TIG welding leads are not supplied with the machine. These are however, readily available from your CLARKE dealer (Part number 6012233)).
GENERAL SAFETY INSTRUCTIONS WARNING: WHEN USING ELECTRICAL TOOLS, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK AND PERSONAL INJURY. WARNING: READ ALL THESE INSTRUCTIONS BEFORE ATTEMPTING TO OPERATE THIS PRODUCT AND KEEP THESE INSTRUCTIONS IN A SAFE PLACE. ELECTRIC SHOCK •...
FIRE OR EXPLOSION Welding can cause fires and explosions. Precautions should be taken to prevent these hazards. • Before starting work ensure the area is clear of flammable materials. • Move any combustible materials to a safe distance, especially substances likely to generate a dangerous vapour.
• NEVER attempt any electrical or mechanical repair unless your are a qualified technician. If you have a problem with the machine contact your local CLARKE dealer. • NEVER use or store in a wet/damp environment. DO NOT EXPOSE TO RAIN.
SAFETY SYMBOLS Read this instruction Do not expose to rain. booklet carefully before use. Wear eye protection Recycle unwanted materials instead of disposing of them as waste. All tools, accessories and Wear protective gloves packaging should be sorted, taken to a recycling centre and disposed of in a manner which is compatible...
ELECTRICAL CONNECTIONS WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS SUPPLY. Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch. If the plug has to be changed because it is not suitable for your socket, or because of damage, it must be removed and a replacement fitted, following the wiring instructions shown below.
CABLE EXTENSION Always use an approved extension cable suitable for the power rating of this tool (see specifications), the conductor size should also be at least the same size as that on the machine, or larger. When using a cable reel, always unwind the cable completely.
MMA/ARC WELDING A consumable electrode is connected to a high amperage low voltage supply which creates an electric arc between the electrode and the workpiece. Benefits over TIG welding include, less experience needed, torch kit or shielding gas are not required. PREPARATION •...
5. Switch ON using the switch located on the rear panel. • The green light on the front panel should glow, indicating the machine is • If the machine stops at any time and the amber light comes ON, the thermal overload device has intervened.
TIG WELDING TIG welding is primarily for very thin materials. It uses a non-consumable tungsten (or tungsten alloy) electrode, held in a torch. A shielding gas (100% Argon), is fed through the torch to protect: • The electrode, • Molten weld pool, •...
TIG WELDING (REF FIG.2) • The machine is not equipped with a TIG welding torch and cables; these are available from your Clarke dealer (Part number 6012232). • Additionally, before TIG welding, you must obtain a gas cylinder of 100% pure Argon.

9. Open the gas valve on the torch handle, • This will allow gas to flow from the torch nozzle. 10. Cover your face with the head shield, bring the torch to within 3-4mm of the work, and at an angle of 45°, so that the ceramic nozzle gently touches the work surface.

WELDING PITFALLS The arc welding technique is an acquired skill and requires considerable practice before perfect results are obtained. The diagrams below will help to explain the pitfalls in your technique and how to overcome them. ARC TOO SHORT This causes irregular masses of weld to be deposited, with slag contamination on an uneven surface.
